Wear history

from Wikipedia, the free encyclopedia

The wear history shows the wear and tear and the associated reduction in quality of objects such as real estate and machines .

The wear and tear is caused by chemical and / or physical processes.

Depending on the intensity of the chemical and physical processes as well as the materiality and manufacturing quality, the following different types of wear and tear result:

  • linearly falling course (e.g. in the case of corrosion processes )
  • progressively falling course (e.g. wear and tear of a facade )
  • s-curve course (mixed form of a degressively falling and progressively falling course, e.g. for a gear )
  • angular course (e.g. LED )

as well as mixed forms of this.

Maintenance measures can positively change the wear and tear.
